Hello first time post. Civic 2005 4 door sedan (si) all of a sudden dead temp gauge + rpm not working and flashing key light.

Lucky the car stars but runs rough (high idle)

Hope someone can help !!

As far as the dead temp gauge, I’d take it to someone who has a D2 sensor. This sensor is able to detect weather something is wrong with the sensor, or the actually thermostat. If it’s either or it’s a simple fix that doesn’t cost too much at all.
I actually very recently replaced my thermostat on my 1.7L 04’ couple because it was heating up.
